1. 判断 访问相册 或 相机 权限是否开启
//在info.plist 里面设置
Privacy - Camera Usage Description App需要您的同意,才能访问相
Privacy - Photo Library Usage Description App需要您的同意,才能访问相册
科普：
相册
//相册权限判断 需要引入框架
#import <Photos/PHPhotoLibrary.h> //相册
PHAuthorizationStatus相册权限状态判断
在8.0系统以后，新加入了Photos.framework框架，我们可以利用框架中的PHAuthorizationStatus进行相册权限状态判断。
判断是否开启相册权限 的4中状态
typedef NS_ENUM(NSInteger,PHAuthorizationStatus) {
//1. 用户还没有关于这个应用程序做出了选择
PHAuthorizationStatusNotDetermined = 0,
//2. 这个应用程序未被授权访问图片数据。用户不能更改该应用程序的状态,可能是由于活动的限制,如家长控制到位。
PHAuthorizationStatusRestricted,
//3. 用户已经明确否认了这个应用程序访问图片数据
PHAuthorizationStatusDenied,
//4. 用户授权此应用程序访问图片数据
PHAuthorizationStatusAuthorized
}PHOTOS_AVAILABLE_IOS_TVOS(8_0, 10_0);
相机
//相册权限判断 需要引入框架
#import <AVFoundation/AVCaptureDevice.h>
#import <AVFoundation/AVMediaFormat.h>
判断是否开启相机权限 的4中状态
typedef NS_ENUM(NSInteger, AVAuthorizationStatus) {
//1. 表明用户尚未选择关于客户端是否可以访问硬件
AVAuthorizationStatusNotDetermined = 0,
//2. 客户端未被授权访问硬件的媒体类型。用户不能改变客户机的状态,可能由于活跃的限制,如家长控制
AVAuthorizationStatusRestricted,
//3. 明确拒绝用户访问硬件支持的媒体类型的客户
AVAuthorizationStatusDenied,
//4. 客户端授权访问硬件支持的媒体类型
AVAuthorizationStatusAuthorized
} NS_AVAILABLE_IOS(7_0) __TVOS_PROHIBITED;

2 、定位
=======检测是否开启定位======
在info.plist 里面配置
Privacy - Location When In Use Usage Description App需要使用定位功能
Privacy - Location Always Usage Description App需要使用定位功能
引入框架
#import <CoreLocation/CoreLocation.h> //定位
遵循协议 <CLLocationManagerDelegate>
typedef NS_ENUM(int, CLAuthorizationStatus) {
//定位服务授权状态是用户没有决定是否使用定位服务
kCLAuthorizationStatusNotDetermined = 0,
//定位服务授权状态是受限制的。可能是由于活动限制定位服务，用户不能改变。这个状态可能不是用户拒绝的定位服务
kCLAuthorizationStatusRestricted,
//定位服务授权状态已经被用户明确禁止，或者在设置里的定位服务中关闭
kCLAuthorizationStatusDenied,
//定位服务授权状态已经被用户允许在任何状态下获取位置信息。包括监测区域、访问区域、或者在有显著的位置变化的时候
kCLAuthorizationStatusAuthorizedAlways NS_ENUM_AVAILABLE(10_12, 8_0),
//定位服务授权状态仅被允许在使用应用程序的时候
kCLAuthorizationStatusAuthorizedWhenInUse NS_ENUM_AVAILABLE(NA, 8_0),
};
【注意】
//1.
//判断定位是否开启是判断的整个手机系统的定位是否打开,并不是针对这一应用
[CLLocationManager locationServicesEnabled]
//跳转到 整个手机系统的“定位”设置界面
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=LOCATION_SERVICES"]];
//2.
//跳转至 系统的权限设置界面
NSURL *settingsURL = [NSURL URLWithString:UIApplicationOpenSettingsURLString];
